“…[52][53][54] Reports of autochthonous leishmanial infections among individuals who have never traveled outside the United States abound. [55][56][57][58][59][60][61] With the effect of climate change contributing to an increased range for sand flies, and flies being found in new locales, in addition to servicemen/women who served in the Middle East and may have been exposed to infection returning home, the opportunity for leishmaniasis in North America to expand both substantially and dramatically is now becoming a reality. 62 It has been recognized that in certain areas of the world, Leishmania infection rates are associated with seasonal variation.…”

Climate Change Contribution to the Emergence or Re-Emergence of Parasitic Diseases

The connection between our environment and parasitic diseases may not always be straightforward, but it exists nonetheless. This article highlights how climate as a component of our environment, or more specifically climate change, has the capability to drive parasitic disease incidence and prevalence worldwide. There are both direct and indirect implications of climate change on the scope and distribution of parasitic organisms and their associated vectors and host species. We aim to encompass a large body of literature to demonstrate how a changing climate will perpetuate, or perhaps exacerbate, public health issues and economic stagnation due to parasitic diseases. The diseases examined include those caused by ingested protozoa and soil helminths, malaria, lymphatic filariasis, Chagas disease, human African trypanosomiasis, leishmaniasis, babesiosis, schistosomiasis, and echinococcus, as well as parasites affecting livestock. It is our goal to impress on the scientific community the magnitude a changing climate can have on public health in relation to parasitic disease burden. Once impending climate changes are now upon us, and as we see these events unfold, it is critical to create management plans that will protect the health and quality of life of the people living in the communities that will be significantly affected.

“…In a marker-releasecapture study, L. mexicana infection persisted in N. micropus for an average of 190 days (range 104-379 days) [32] with a mean follow-up of 8.2 months. There is some debate about additional vertebrate hosts; McHugh surveyed 100 cotton rats (Sigmodon hispidus), 60 opossums, and 20 armadillos in Texas and found no evidence of leishmaniasis [34]. In northeast Mexico, a systematic ecology survey collected 79 specimens of nine vertebrate species, where the most common samples were Peromyscus maniculatus (38%), Sigmodon hispidus (30%), and P. leucopus (16%).…”

Leishmaniasis, a chronic and persistent intracellular protozoal infection caused by many different species within the genus Leishmania, is an unfamiliar disease to most North American providers. Clinical presentations may include asymptomatic and symptomatic visceral leishmaniasis (so-called Kala-azar), as well as cutaneous or mucosal disease. Although cutaneous leishmaniasis (caused by Leishmania mexicana in the United States) is endemic in some southwest states, other causes for concern include reactivation of imported visceral leishmaniasis remotely in time from the initial infection, and the possible long-term complications of chronic inflammation from asymptomatic infection. Climate change, the identification of competent vectors and reservoirs, a highly mobile populace, significant population groups with proven exposure history, HIV, and widespread use of immunosuppressive medications and organ transplant all create the potential for increased frequency of leishmaniasis in the U.S. Together, these factors could contribute to leishmaniasis emerging as a health threat in the U.S., including the possibility of sustained autochthonous spread of newly introduced visceral disease. We summarize recent data examining the epidemiology and major risk factors for acquisition of cutaneous and visceral leishmaniasis, with a special focus on implications for the United States, as well as discuss key emerging issues affecting the management of visceral leishmaniasis.

“…This case highlights a unique opportunity to discuss cave exploration, in endemic regions, as a high-risk exposure activity for the acquisition of infection with leishmania. where it is acquired endemically more frequently than it is via travel [3,4,7]. In contrast to Old World species infections, cases of leishmaniasis caused by L. mexicana, may have a diverse clinical presentation including papular, nodular, or ulcerative dermatosis.…”

Cutaneous Leishmaniasis due to Leishmania mexicana is a common cause of New World protozoal infections endemic to southern Mexico and now the United States (US). We present a case of a 72-year-old male who became infected with cutaneous L. mexicana while participating in numerous diving excursions in the flooded limestone caves, commonly referred to as cenotes, in the Yucatán Peninsula. This unique case of adventure tourism highlights cave diving in endemic regions of leishmaniasis as a possible new risk factor for the acquisition of this disease. We also discuss increasing autochthonous cases of cutaneous leishmaniasis and the different barriers to treatment that occur with this disease.
